Vahana Mandapam Entrance to Amruta Kalasa
You can find the other entrance to Amruta Kalasa Garudan Sanctum in the above picture,
( the sanctum behind the tree ).
Amruta Kalasa Garudan here has Amruta Kalasa (nectar filled pot) on his right hand, as found in below picture.
If you can see, garudan has a serpent on his left hand, which indicates all the sarpa doshas are healed by Garudan found in this sanctum, and in general, Garudaazhwaan cures Sarpa Dosha.
Since Garudaazhwaan is a vehicle for Lord Sriman Narayana, he is found with folded hands (Anjali Mudra), with all humility towards the lord.
There is also a board outside, opposite the main sanctum, which indicates the benefits of worshipping Lord Garuda on each day of the week.
